It’s a touching moment when a three-year-old beams with pride as she meets her little sister for the first time in the hospital. In the footage, which has since received more than 27,000 views on social media, older sister Molly of Wynnewood, Pennsylvania holds her newborn sister Cora tightly in her arms and can’t take her eyes off the new bundle of joy.

As the toddler gently strokes the baby’s head and offers her a few kisses, Heather Conley’s mother can be heard saying to her baby, “Be gentle.” Knowing that she has to be gentle with a small child, Molly tells her new sister, “You just came out of your mother’s belly. I won’t leave you… I won’t let you go again.
